To all 'whom t may concern: i

' Be it known that'l, PETER HovLANm' a' citizen of the United States,r'esi'dingl'at Minnesota, have invented certainnew and useful'Improvements in Spring? Wheels and I do'hereby declare the following tobe a full,I clear, and.'eXact desfription' of the in the art to which itappertains to make and T his invention' relates to; im rovements inyvehicle wheels, and more particularly lto the o neof its-objects to imrove the construction and increase' the ve ciency and utility Anotherobject of the invention is toiprosilent rimformed in sections'andresilient one or more of the sectionsof the rims or one or more ,of thespokes may be renewed withoutjdiscarding the remainder vof ithe wheel. A1

With these .andother objects in view they invention consistsincertainnovel features;` of construction as hereinafterM'ShOWnand described andspecicallypointed out in the the preferred embodiment ofthe invention. lFigure l is a side elevation partlyingsecline y2 2 `of Fig. 1. Fig. 3"is ja view similar The limproved vwheel comprises 'a lh iib ortion,which may be*v constructed-in any desired manner, butfor the purpose ofillusnumber of radially disposed spokes 11, the latter being rela-tivelyshort and with the' outer portions formed with vparallel sides, as

The rim ofthe wheel` is formed of a pli i i ralityof sections 'of coiledwire, with their ments of the wheel, as 'hereafter eXplaind. Arranged atintervals between vthe rim rods equal in number to the spoke elements 1land arranged in/longitudinalalinement therewithasshownf The 'outer endof each rodisreduced or.t apered as shown at 13, and attached to., `the'sides of each rod are clamp ,members 'lll- 15, the clamp members-riyetedkor other-wise securedi'at 16 to the'rods and with their outerends y. curvedto conform to the outer. surface7 of the-rim, tl1e vcurvedportions extending beyond the cen-l each of thespoke elements 11 anditsl rods n 12 is a spring 19, tlieouter end-of each spring secured,preferably by riveting as shown-at 20, to the/rod, andthev inner end..securedpreferably by"ri veting at 21 to thespoke element. Surroundingthe outer end of each of the spokes 11 and the" inner end of each .ofitscorresponding rods 12 is a sleeve 25 the sleev coactingewith thespoke andthe.

rod andt e spring 'to retain theparts 'in po- Asl before mentionedA therim is formed of a plurality of coilsof wire 22 arranged 'end toend-with theends of the coilsbearing between the y clamp members'14T-45, the 4terminal helix of each 'coil being riveted as shown at 26,to Yone of the clamp plates. By this means in eventof thev breakage orimpairment of one or more of the-coiled sections sition. By this meansthe rim 22 is firmly coupled yieldably. to the. hub at intervals coriresponding to the spoke elements '11,

sol

22 the impaired section may bereadily def# tached by driving out therivets 26 by which .it is .connected to the clamp plates' 14; andinserting a new coilsection, and without discarding or interfering" withthe vremainder. yof the wheel. rI his is an important advantage in1the-improved device, as will be' obvious. n The improvements hereindescribed may be readily applied to wheels of various sizes land ltowheels'employed for. various purposes, but is more particularlyapplicable to wheels of automobiles, and similar vehicles.

The resilient -rim members may be provided with 'a core offlexible-elements' such as rope or thelike which will efectually preventrattling or looseness while at the same l A time not interfering withthe yieldableness of the structure, and forthe purpose of illustrationthis filling material is represented at 27, but it will be understoodthat the invention is not necessarily limited to the` emhelically Woundsections arranged .end to i j clamping means betweeneach of said spokes-..,cal mm sections.A -v
